 Cool Riders
 Sega 1994
 
-This game runs on SYSTEM-H1 hardware. Only one known game exists on this
-PCB and this is it. The hardware seems overly complex for a 2D bike
-racing game? The design of the PCB is very similar to vanilla Model 2
-(i.e. Daytona etc). However instead of fully custom-badged chips,
-many of the custom chips are off-the-shelf Hitachi/Toshiba gate-arrays.
